Louisiana-Pacific Corporation (NYSE:LPX): “Recently, we have seen some hopeful signs of growth in the North American housing market, which is good news,” stated CEO Rick Frost. “Because the economy is still fragile, with slow job growth and little progress made to address our country’s underlying fiscal issues, we are planning on a slow recovery in 2012. Fortunately, our financial situation allows us to be prepared to satisfy market demand if housing is better than we expect,” concluded Frost. The shares closed at $8.26, down $0.62, or 6.98%. They have traded in a 52-week range of $4.41 to $11.63.
